FEED CUT'l'ER QFECIFICATION forming part of Letters Patent No. 380,966, dated April 10, 1888.

Application filed December 11, 1885. Serial No. 185,350. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM E. WHITMAN, of Winthrop, in the county of Kennebec and State of Maine, have invented a new and useful Improvement in FeedGutters, which irnprovement is fully set forth in the following specification and accompanying drawings, in which- Figurel is a sectional view on the line [050, Fig. 2. Fig. 2 is a frontview looking toward or into the mouth of the cutter. Fig. 3 is a front view, having partof the box (2 in section. Fig. 4 is a plan View of that part of the cutter to which my invention relates, and Fig. 5 a section on the line y y of Fig. 4.

Like letters and figures indicate like parts.

My invention relates to that class of feedcutters which have pivoted knives and are operated by a hand-brake, and is confined to the means by which the pivoted end of the brake is secured to the frame-work of the cutter.

The object of my invention is to so construct this connection that the brake and knife may be easily detached, that the bearings may be kept firm, and that the whole may be so adjusted that the knife is kept close to the mouth of the trough and the feed readily cut.

a a are theposts upon which the cutter stands.

' b b is the plate, secured to the frame-work by bolts 4.

0 0 0 indicate the mouth of the trough, through which the feed is passed to be out.

n is a plate cast integral with the brake f, and covering the mouth 0 0 0 when the brake is pressed down, and thus preventing the feed sliding through.

9 is the knife, secured to the brakef by the bolts 10 10. This knife is secured on the back of the brake f and extends below the plate it, thus bringing the back surfaces of the plate n and knife 9 in a plane with each other and fitting close to the mouth 0 o o.

It will be seen that the plate a may be se cured to the brake j" with bolts, if desired; but I prefer casting them together.

In Fig. 1, 4 is one of the bolts by which the plate bis secured to the post (1. Upon this plate is cast the bracket 3, which has a lip, 11, projecting upward, through which passes the set-screw 3. Upon this bracket rests the box d, having two upwardlyprojecting sides, 2' t,

separately and secured by any convenient de- 7 vlce.

Through the side 2" of the box d passes the set-screw 1 into the head 6. 5 is a nut to prevent the set-screw 1 becoming loose. posite end of the head 6 passes into the side 2" of the box d, as indicated. The box dhas cast thereon the downwardly projecting lip 11, through which passes the set-screw 7 against the bracket 8, as indicated at 8, Fig. 2, the lip 11 being located at the outer end of the box d. It will be seen that this box, being secured to the bracket 8 by the bolt 2, may be turned thereon, and this may be accomplished by the action of the set-screw 7 through lip 11. The slot 00 is out part way in the bottom of the box d, of awidth sufficient to allow the head of the bolt 2 to drop into it and have it flush with'the top. The rest of the slot which is cut through the bottom of the box is narrower, but of suf- 'ficient width to allow the shank of the bolt 2 to pass through it and permit the box to slide there over when the set-screw 3 is operated.

m m are the sides of the slot, and m m the shoulders upon which the head of the bolt 2 rests.

It will be seen that by loosening the set-screw 1 the brake may be removed and the knife sharpened. It may then be adjusted in the bearings,and the screw 1 set up, so that thehead e is held firmly between the sidet'of the box (Z and a seat in the side t" of the box. The nut 5 is then turned up, so that the set-screw will not work loose.

To adjust the knife accurately to the plate I), the nut 6 and set-screw 7 are loosened. Then by turning the set-screw 3 the box dis moved, (the bolt 2 passing through the slot 00,) so that the knife 9 is brought close to the mouth 0 0 0. There will be a tendency in the brake and knife at the free end to swing off from the mouth 0 0 0, leaving a space between the knife and the mouth, in consequence of which the feed will not be cut. This is obviated by the set-screw 7, which passes through the downwardly-projecting lip 11 and against the bracket 8.

The op-' setting this screw up the box is turned upon the bolt 2, and this, it will be seen, throws the free end of the brakef, and consequently the knife 9, against the mouth 0 0 0 and holds it firmly. Should the knife be too close to the mouth and there be a tendency to cut into the plate b and dull the knife, it may be remedied by loosening the screw 7, which would allow the brakef and knife 9 to swing away from the mouth 0 o 0. The nut 6 is then set up and the whole secured.

The lip c and set-screw 3 may be omitted and the adjustment made by sliding the box (I on the bolt 2 and setting the screw 7. By this arrangement a very strong cutter is made, the knife is readily removed for sharpening, the whole is quickly adjusted, and all wear in the parts is taken up by the set-screws, and the several parts will not become so worn as to prevent the cutting of feed.

In casting, the bearings of the head eand the upright i are chilled, so that there is very little wear.

I claim as my invention- 1. In a feed-cutter, the combination of the brackets, the box d, having the slot as in the bottom thereofand the downwardly-projecting lip 11 thereon, the brake f, having the knife 9, attached thereto, pivoted in said box, the set-screw 7, passing through the lip 11 and against the bracket 8, and the bolt 2 and nut 6, for adj ustably securing the box to the bracket, as fully described and set forth.

2. In a feed-cutter of the class described,the combination of the face-plate I), having the bracket 8 cast integral therewith, the box d, having the downwardly-projecting lip and the slot cut in bottom thereof, the set-screw passing through said lip against the brackets, and the bolt 2 and nut 6, for adjustably securing the box to the bracket, as fully set forth.

3. In afeed-cutter of the class described, the combination of the brackets, having thereon the upwardly-projecting lip c, the box d, with slot a cut in the bottom thereof, the set screw 3, passing through the lip 0 against said box d, and the bolt 2 and nut 6, for adjustably securing the box to the bracket, as fully described.
